| 摘 要： | 提出一种新的随机多址接入时隙分配方法,对碰撞事件和空闲事件分配短时隙,优点是碰撞事件可以提前中止,空闲期也避免累积更多的竞争报文,对成功事件分配长时隙,既能保证一个完整的报文不间断发送,同时也提高了信道的吞吐量。用平均周期分析方法研究系统特性,通过数学建模分析,得到了信道的吞吐量解析结果,理论分析与仿真实验一致。

| Abstract: | A new method for allocating slots in random multi-access channel is presented. Collision or idle events are assigned short slots, which make early termination for collision events,and avoid the accumulation of competition packets on idle slots. At the same time, long slots are allocated to successful events, which ensure that the transmission of complete packets is uninterrupted, and improve the channel throughput. The average cycle analysis method is used to system characteristics discussion. By mathematical modeling and analysis,channel throughput is obtained,and theoretical analysis and simulation results are consistency. |
